@adytum_official: hEDS has been classified as a connective tissue disorder, but patients keep reporting immune symptoms (allergies, mast cell issues, autoimmune diagnoses, chronic inflammation) that the connective tissue model doesn’t fully explain. A 2025 study by Griggs et al. in ImmunoHorizons ran an unbiased serum proteomics screen on 29 hEDS patients vs 29 matched controls. They found 35 proteins that were significantly different between the two groups. 43% were part of the complement cascade (a key inflammatory pathway), and 80% were linked to immune, coagulation, or inflammatory pathways. Almost none of the differential proteins were collagen-related. Cytokine profiling confirmed an immune-dysregulation signature. This is single-lab early-stage research that needs replication in bigger and more sex-balanced groups. The study didn’t comprehensively measure all collagen-related proteins, so this finding adds to the picture of hEDS rather than replacing the connective tissue piece. Not a clinical diagnostic. I’m not a doctor, just sharing research I find interesting. Sources: Griggs et al. (2025). Proteomic discoveries in hypermobile Ehlers-Danlos syndrome reveal insights into disease pathophysiology.

EDS is such a strange mysterious disorder. Lots of comorbidities that go along with it that don’t make sense. Like most of us being neurodivergent, and HSP. It’s very strange.

As an hEDS patient, I just wish I'd meet with a doctor that actually knows what EDS is 🙃

OK, I have EDS. I think it's an interesting question to consider why, like hEDS also causes significant physiological stress which lights up those immune pathways, it's a cascade. A causes B, C, D, and E

I can’t wait for someone to figure out why GLP1 makes such a huge improvement for all or most of these conditions.

I was already Dx but can someone tell me why my lab work keeps coming back basically saying I’m the picture of health? Like I don’t care what that paper is telling you, I AM TELLING YOU I FEEL LIKE 💩! There’s no way I have no inflammation in my body. There’s no way my liver and kidneys and m

Anyone else here with hEDS also have HG in pregnancy?!?

Vincent :
could it be that hEDS is a result of our immune system instead of ligament growth? 🤔 it would make sense why a lot of people end up with MCAS.
reversing the cause and effect.

Please be careful with the way you word these things - HEDS IS a connective tissue disorder. Collagen is only one part of the connective tissue system and connective tissue makes up a huge proportion of our tissues, including heart, brain, muscle, and vascular tissues, blood, hormonal structures and more. Collagen =/= all connective tissue, it IS a connective tissue disorder, it is NOT a collagen disorder.

I’m confused because I was diagnosed by a geneticist over a decade ago, and other than the piece you said about collagen, the geneticist told me all of that. He even diagnosed me before measuring the extension in my joints and check my flexibility. The hypermobility was basically an afterthought— also why I hate that it was renamed hEDS.

I have extra myelin in all of my neurons. It's neurological. No one wants to address that.

why is this the first time they've looked at it without bias...

also good to note that blood is considered in itself a connective tissue

Shout out to people in the UK with this hEDS ! Can anyone provide us with information on where to go for diagnosis and help?

29 is a very low number of participants for a clear definition of scientific evidence

Interesting!! I am dx hEDS and collecting auto immune disorders. Most interestingly APS. I wonder how common APS is in hEDS population since it’s so rare otherwise.

Definitely sounds like it makes sense, Definitely needs repeating.

The immune system, fascia, nervous system, lymph etc are all interconnected. Mast cells exist within the fascia

Another issue, in the UK, there are limits of the kinds of labs that can be ordered by a GP, and restrictions get tighter, you see an actual doctor less and less, and referrals are now harder to get. So frustrating

This really makes me wonder. If this is a basic amino acid, like basic building block problem, which to some degree, I realize is asking chicken or egg. But it's gotta go deeper than that

I saw Sarah Schauer (I think, forgive if I misquote) say from her research that blood TECHNICALLY IS connective tissue and a lot of people/the literature doesn’t understand that
